METALLIC WHEEL.

SPECIFICATION forming part of Letters Iatent No. 429,253, dated J une 3,1890. Application filed October lJ 1889. Serial No. 325,633. (No model.)

To cLZZ whom it may concern:

Be it known that I, EDWIN DAVID VAS- SELL, a citizen ot' the UnitedStates, residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inMetallic Vehicle-VVheels; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to vehicle-wheels, and has for its object certainimprovements, which will be hereinafter described, and particularlypointed out in the claims.

In the accompanying drawings, which form part of this specification,Figure l represents a vertical longitudinal section of my improvedwheel; Eig. 2, a vertical transverse section through the hub on line ccw, Fig. 1; Fig. 3, a side elevation of the aXle-boXgiand Fig. 4, alongitudinal section through the box at the outer end of one of thespokes, showing the spoke in side elevation.

Reference being had to the drawings and theletters thereon, A indicatesthe hub of the wheel, which is formed of tubular .sections a, sectionI), and lining c CZ in each of said sections, respectively, made ofwood, and a'n outer casing e, made in two partsf g, connected byscrew-threads atA h, and each section f g is provided with annularinwardlyproj ecting sockets c', which surround the spokes and form abearing therefor.

At the inner end of wooden linings c (Z are metallic rings Z fm, andmidway between said rings is another ring n, the three rings forming thewalls of spaces around the axle-box B to receive iillings o p, ofrubber, lead, or other analogous soft metal, in which the inner ends ofthe spokes Zo are seated. Around the middle ring n and between the twosets of spokes of the'wheel is a ring q, of wood, against which theopposite or inner sides of the spokes bear.

In constructing the hub of the wheel the linings c d are driven into thesections ab, the former being provided with a groove o' s, respectively,into which the metal of the latter is compressed circumferentially at ta to secure the linings in the sections. The linings having beenproperly bored to receive the axle-box B, the rings Z m are placedintheirrespective sections and the ring n of the axlebox. The sections aI), with their linings, are driven upon the axle-box, and the spacesbetween said rings filled with lead or analogous soft metal. The woodenring q is then placed in position, and the outer casing c is applied,and the hub rmly secured together.

Through the outer casing c are holes to rei ceive the spokes, and in thelead iilling are formed annular seats n to receive the inner ends ofthespokes. The spokesbeing seated in lead or other soft metal, theringing sound of the spokes due to their vibrations when in motion -isdeadened by the lead.

The outer end of each spoke is reduced in diameter and a spiral groove aformed thereon, and around said end is placed a box b', which conformsto the inner surface of the hollow telly c', and is filled with softmetal CZ', rubber, or other non-conductor of sound,

which acts in conjunction with the lead in the hub at the inner end ofthe spokes to deaden the noise or sound produced by the vibration of thespokes.

also preferably made of the same material.

C indicates the tire, which is applied to the wheel in a heatedcondition and then shrunk thereon.

The linings c d and the ring q may be made of compressed paper-pulp,which is a noneonductor of sound,`and further contribute to renderingthe wheel noiseless.

The rings Z, m, and n may be cast together by a web connecting them, ifdesired, and the inner ends of the spokes may be filled with cork,rubber, or other non-conductor of sound, as shown at c in Fig. 2, andthe spokes may be provided with a spiral groove at their inner ends toembed in the rubber or lead in the hub.

In the use of rubber or lead filings or other analogous metals thevibration of the metals composing the wheel is prevented, andconsequently any tendency of the different parts of the steel wheel tocrystallization is prevented.

It will be noticed that when the inner ends of the spokes are embeddedin 'the hub the The spokes are preferably made of steel tubes, and thefelly is f IOO force necessary to embed them will cause the lead to fillup the inside of the end oi the tubular spoke to the same depth asaround the outside, as indicated in Fig. l.

Then the different parts of the hub are put together and the outersleeve put on and screwed together, the spokes are then put in the hub,and on account of being placed alteruately on either side of thethread-joint of the ou ter sleeve of the hub Will prevent the outersleeve from slackening and coming apart, as the spokes, on account oftheir relative positions, Will form a perfect lock In constructing theouter casing c, made in two parts, the metallic sockets -i may, ifdesired, be left off, or they may be set back in the space, so as toleave room for a ring of wood in each section of the outer casing, whichwould be the same as ring q; or the entire outer casing may be filledwith wood in the inside, and when the hub is put together the holes maybe bored out in the Wood down to the lead rings for the spokes to passthrough the wood and enter the lead.

Having thus fully described my invention, what I claim is 1. In ametallic vehicle-wheel, a metallic hub and a metallic felly, incombination with tubularmetallicspokesliavingtheirinnerends filled Withand embedded in soft metal, rubber, or other non conductor of soundcontained in the hub and surrounding the end ot' the spokes,substantially as described.

2. In a metallic vehicle-wheel, a hub formed of tubular sections havinga lining, a softmetal filling to receive the spokes, and an outer casingprovided with holes for the spokes, substantially as described.

In a metallic vehicle-Wheel, a hub consisting of lined tubular sections,a sott-metal filling in which the spokes are embedded, and an outercasing provided with inwardly-projecting sockets, substantially asdescribed.

4. In a metallic vehicle-wheel, tubular inetallie spokes having boxes attheir outer ends filled witlrsoft metal, rubber, or other nonconductorof sound, the ends of the spokes being embedded in said material andsecured againstlongitudinal movement and contained in the felly of theWheel, substantially as described.

5. In a metallic vehicle-wh eel, hollow spokes having a spiral grooveformed in their outer ends, in combination with a box and a filling ofsound-deadening material Within the felly of the Wheel, substantially asdescribed.

(i. In a metallic vehicle-Wheel, tubularsections and linings having acircumferential groove, in combination with a depression in the sectionsengaging with the grooves in the linings, substantially as described.

In testimony whereof I atiix my signature in presence of two Witnesses.
